l SPECIFICATION forming part of Letters Patent No. 381,017', dated April 10l 1888.

Application filed September 6, 1886. Serial No. 212,876. (No model.) 'Patented in England March 25, 1885, No. 3, 8,30; inFrance October 10, 1885,'N0. 171,588; in Belgium October 12, 1885, No! 70,457, and in Germany October 21, 1885, No. 4,039.

T all wiz/0711, #may concern/e Be it known that I, JOHN JACKSON, a subject of the Queen of Great Britain, residing at Springfield Gravelly Hillnear Birmingham,

England, mechanical engineer, haveinventeda Spring-fire Band, (for which l have applied for Letters Patentin Great Britain, No. 3,830, dated the th-day of March, 1885; German Empire October 21, 1885, No. 4,039; Francek roOctober 10, 1885, No. 171,588; Belgium October 12, 1885, No. 70,457B,) of whichthe foll lowing is a specication.

My invention relates to the construction or formation ofan open-worked spring or yield- 1 5 ing band to be'used in the formation or inaking up of bedsackings, 4mattresses,.chair and other seatings, and' for various other articles for various purposes.

The said yieldingband, oftwoormore lengths,

20 of which my web is made is formed or made from a continuous length of spring-wire, which is so fashioned that the wire crosses itself obliquelyin passing from opposite coils or twists, which form the'edging to the baud.` The coils 2 5 or twists are formed', preferably, upon pegs.l The said band possesses all the advantages 'of an elastic'or rubber band without its disadvantages in respect of deterioration from change of temperature and from other causes;`

3o and the object of my said invention' is the production ot' a cheap open-work elastic wire banding that will neither deteriorate when in use nor overstretch when distended. f

. I will now proceed to describe, with refer- 3 5 ence tothe accompanyingdrawings, the man,-

vner in which the same is tobe'performed. l

Figure 1 represents in front elevation an open-work flexible or yielding wire-spring baud. Fig. 1"n is a portion of the same upon a 4o larger scale. Fig. 2 is a vertical section upon the dotted lines A B, Fig. 1. Fig. 2 is a vertical sectional view of Fig. 1a. Fig. 3 is a horizontal section upon the dotted lines C D, Fig. 1. Fig. 4 shows the ,bandFig 1 proi vided with a check orglimiting cordstrung or threaded through the eyes of the coils to prevent the overstretching or overdistention kof the band. Fig. 5 is an edge view, and Fig. 6'

is an end view, of thesame. Fig. 7'shows the 'band Fig. 4 distended or stretched.` Fig.- 8` 5o is an edge View, yand Fig. 9 is an end view, of e the distended band. Fig. 10 shows a series of the bands Fig. 1 placed side byside and eon .nected togetherL so as to form a broad band. y Fig'.`11 shows a metallic seating or sacking 55 ,x

formed from taper or graduated bands placed.

togetherand radiating to or from a center.. The 5 i. `V

said bands are connected together by the checklimit their diste'nt/ion. y l The same letters of reference indicate corresponding parts in the several iigures' of the drawings; y

The open wire-work'vband Fig. lis made preferably from a single length of harddrawn 6 5 'y or spring wire bent zigzag or crosswise in an advancing direction,with`coils ortwisted loopsv at the return ends of the crossing wiresg-gthat is, a length ofspring-wire is wound or coiled around pins or pegs placed atvsuitable distauces apart, according to the design required. l:

The band is made and fashioned in design by twistingmhe wire first around one ofthe pegs, n n n so as to make two or more coils, then bringing the wire crosswise to another peg onthe opposite side, and winding the same number of coils around it as on the opposite one, the" wire stretched between the two coilslying in a diagonal orinclined direction. The wire is again brought backin a reverse direction, so 8o as to make theLwires cross each other and'form' an open-worked band with single, doub1e,'or quadruple coils upon itsA outside edge, .while thewires which lead'to and fromfthe coils cross each other in a diagonal direction. I 85 p A are double coi1s,',loops, or twists, and bare cross-wires or spring'arms leading'to and from the coils A. f f

O is'a check-cord, which is threaded orinterlaced through theeyesof theloops or coils 9o..

in suchV a manner Vthat the interlacing'slie loose when the band is in its normal or non'-v distended position, and forms an ornamental edging, but when the bandis distended it limits or prevents kits overstretching; 'The terminal 95- ends Cz of the ch eck-cords are fixed or attached to the terminal ends of a band or the terminal ends of a. series of bands.

Having thus described my invention, I claim and desire to secure by Letters Patent- 5 1. Asa new article of manufacture, aspringwire net or mat composed of several widths of similarly-coiled wires united at their edges by yielding continuous connections passing through the eyes of the coiled wire, substanro tially as described.

2. As a. new article of manufacture, a spring- Wire net or mat composed of several tapering Widths of wire band united at their edges by yielding connections, substantially as described.
